If it is said that in this Northern Expedition, the 20,000 horses led by Huang Jie are the elite of the elite, then the Song army that has appeared in Yaozhou now can be said to be the "elite" next to the "elite of the elite".

As mentioned above, the soldiers used in this Northern Expedition are mainly divided into three levels, the first class is naturally Huang Jie's front army, and the Chinese army stationed in the base camp is the elite carefully selected by the division of the 200,000 Qinwang of the year, which is considered the second class. As for the third-class Lingbao guard troops, which are specially trained, they are all Hebei recruits.

Of course, in addition, there is also the fourth class, that is, the army that is now personally led by the seed master Dao in Hebei, recovering Yandi and winning the pass, although all of them are veterans and defective products that cannot enter the first and second class troops after selection, but the combat power is also difficult to discount.

After all, on the battlefield, one veteran can be said to be better than ten recruits, and if it is a veteran oil, I am afraid that the combat power is stronger than that of ordinary veterans.

Moreover, in addition to the fact that this army itself is elite, coupled with the fact that it has undergone several years of careful training and conditioning in Hebei, if its combat effectiveness is still inferior to that of ordinary border troops, wouldn't it become a big joke?

And at the moment, it is not a new tactic used by the Song army to deal with Tie Ulu, but it is the rifle that the Western Army has used for almost a hundred years to resist the cavalry attack.

The so-called refuge formation, also known as the "palace rear" formation, is a battle formation composed of rearguard troops, which is mostly deployed behind the large formation of the Chinese army to prevent the enemy from attacking from behind. Most of the military generals of the Song Dynasty believed that in the case of "the system of the military formation, the grain road is in the rear", in order to prevent the "grain road from being cut off", it is necessary to refuse the rear formation.

Therefore, it is recorded in the "General Essentials of the Martial Arts" that the failure of Song Taizong's several battles against Liao is related to the "grain road" being "cut off" by the enemy. Starting from the true sect, attention was paid to placing "the palace of soldiers" so that "it could be used in a hurry and without the trouble of suffering from the enemy".

And now, the Song army team set off to Tangchi Fort to Qingshi Fort, because all kinds of vehicles carrying materials must take the road, so it is natural to line up the soldiers on both sides of the road.

But he also said that at the same time that Tie Wulu was annoyed and stunned, Song Jun saw that Jin Jun had run back five miles away, and he actually moved again. I also saw that the first, second, and third rows of foot shield men who had lined up in the shield array shouted slogans and got up in unison, the third row erected the spears on the shoulders of the second row, and the second row also erected the special spears on the shoulders of the first row, and the people in the first row walked to the front of the horse rejection pile with their shields and quickly disassembled, and then carried the guns and walked back to the queue, and the last row of crossbowmen also moved in front of the three rows of foot shield bearers at the same time, slowly got up and took back the arrows planted in front of them to the ground back to the quiver, and then shouted the trumpet and continued to march along the road in the direction of Tangchi Fort.

Seeing that the Song army didn't want to delay the march for a moment, Tie Wulu was obviously also angry after being obviously stunned, and immediately rubbed his fingers into a whistle, and ran towards the Song army again with a roar.

But this time, it wasn't until Tie Ulu led a thousand horsemen and horses into the three and a half miles and a half that he saw the Song army shouting loudly, and then he repeated the steps of setting up horse rejection stakes, setting up gun arrays, and inserting arrows.

Since the spears and special spears on the side of the Song army for the first time were assembled on the spot, and now they are all ready-made, so this time when they saw the Jin army rushing again, they naturally did not panic, and almost all of them completed all the preparations in accordance with the regulations, and when Tie Wulu and they ran into the critical point of the charge in Erli again, the Song army was also ready again.

Again, Tie Wulu naturally didn't find a chance, so he could only whistle and lead the team to turn, and when he led the people back to the position of five miles and stopped, he also saw that the Song army actually dissolved the formation in an orderly manner, and marched forward with neat and small steps.

Of course, you must know that before the Jin State, the Song army had fought fiercely with the Liao State for more than a hundred years, and had also fought with the Western Xia for decades. If you see a cavalry army attacking and disturbing, you will panic and form a formation to defend yourself, and then you will be too frightened to continue marching, then such a team will have been eaten to the point that there will be no bones left, how can it appear in the hinterland of this Jin country?

The two temptations were fruitless, and Tie Wulu also knew that he would not continue to test the value of the Song army, so he could only return with regret and send the news that this army was suspected to be the elite of the Song army.

The news was reported to Zong Wang, and Zong Wang was not surprised after hearing it, thinking about the attack of the Song army this time, it would be strange if it was not for the elite with it. Soon, Tong Ulu, who was ordered to go to Yundao to investigate, also sent someone back to send back the news, saying that Yundao was facing the mainland, but it was seen that there were Song warships constantly unloading and landing Song soldiers from the shore and the sea.

Speaking of this time, the cloud island is not like the later generations, because the water and soil siltation has been connected with the mainland, and it is still an independent and seaside island, the area of the island is about more than ten miles in size (the later generations of Lianyun Island is only 4X3 kilometers in size), plus surrounded by the sea, for the Jin army without a naval army, it is just an aircraft carrier for the Song army to land on the mainland as a springboard. Even if the Jin army wants to sneak attack, they can only look at each other across the water when they get closer, are they still afraid that they will be able to fly to the island with wings?

Not to mention what Zong Wang would think after hearing that the Song army was still continuously increasing troops to the mainland from Cloud Island, he also said that although it was still freezing today, it was rare to show the scorching sun, and the sun was shining on the body, so the generals of the Jin Army looked outside the camp for more than an hour, anyway, it was good to bask in the sun, just come and see the movements of the Song army.

However, the more everyone looked, the more chilled they became, and they saw that after the Song army spent almost an hour and a half, the vanguard finally arrived at the foot of Tangchi Fort.

On the contrary, the carriage in the middle of the road, after arriving, quickly unloaded the goods under the southern corner of Tangchi Castle, and turned to Bluestone Castle.

When the Jin army first came to see, they were a little unclear, but after looking at it for a while, they were collectively stunned to find that Song Jun's actions were actually to use people to form a human wall between Qingshi Fort and Tangchi Fort to protect the heavy vehicles transported on the road.

Calculated that the distance between the two fortresses of Qingshi and Tangchi is really not long, and if an average of 300 people join hands together is one mile, it will only take 6,000 people to form a 20-mile-long human city wall. In fact, if it is really pinch the head and remove the tail, and then count the Jin army's attack at least to enter the range of at least five miles before it is possible to launch a surprise attack, then the length of this human city wall is only less than ten miles, and even if 10,000 people march in two rows, they are only afraid that it will stretch for ten miles (one meter apart per person), so it is not difficult to do this.
